Members Kdogg Posted October 23, 2005 Members Share Posted October 23, 2005 Just wondering if any of you sm-500 owners are running your amplifier in stereo mode with 8 ohm cabs (2 4x10's) ? If so, are you finding that you get enough volume and punch? I'm currently running my two cabs bridged mono for a 4 ohm load. It sounds great, but man does that amplifier get cookin'! I'll probably add a rack cooling fan at some point, but I read in the bass amp review section, that one gentleman was running his sm-500 in stereo so the amp didn't have to work as hard. Thought I'd give the specs: POWER (minimum):Bridge/Mono Mode500 Watts @ 4 Ohms400 Watts @ 8 Ohms250 Watts @ 16 Ohms(minimum load = 4 Ohms) Stereo Mode (per side)300 watts @ 2 Ohms250 watts @ 4 Ohms150 watts @ 8 Ohms(minimum load = 2 Ohms) Link to comment Share on other sites More sharing options...
Members fretless Posted October 23, 2005 Members Share Posted October 23, 2005 I say 250 watts will not quite do it , but you need to try to see , if it clips too often that could be bad , I use a Stereo 800 and @ 350 watts a side @ 4 ohm it will clip sometimes , I use it at it's full glory , 800 watts @ 4 ohms bridged , and use a fan , no worries Link to comment Share on other sites More sharing options...
Members Kdogg Posted October 23, 2005 Author Members Share Posted October 23, 2005 Actually Fretless, it would be even less watts. With an 8 ohm cabinet, and running in stereo mode, the amplifier is only putting out 150 watts/side. I just don't think that's enough power to run the cabinets effeciently, but maybe I'm wrong.

Members fretless Posted October 23, 2005 Members Share Posted October 23, 2005 ah I was thinking you would just use 1 side @ 4 ohm , but the manual says 2 ohm min , and then says "damage will occur " if below min , but then it says "if you use just one side " , so I can't tell if it's safe to use only 1 side or not I use my Stereo 800 sometimes 1 side only , but the manual clearly states that it safe to do so . So I say use it bridged and find out if it's safe to use 1 side just to know, but even at 250 watts it may not do it for ya , at 150 vs. it's full 500 watts , I say 500 baby ! Get a fan if you are worried about heat , but run that amp , those cabs want to see some power , clipping the amp for to long can damage them , so if 150 a side is loud enough for you and no steady clipping occurs then perfect , you can add more cabs per side down to 2 ohm I would say 1 x 410 cab bridged at 8 ohm at 400 watt would also kick ass Link to comment Share on other sites More sharing options...
